Abstract:

The use of physical harriers between loin. cubes of a semi. synthetic diet allowed mass rearing( of pink bollworms, Pectinophora gossypiella (Saunders). A layer of nonabsorbent cotton was the most effective harrier. A negative, highly significant correlation between number of larvae and percent moisture of medium was obtained for diets with 76 and 84% moisture. Medium containing 75% moisture produced the highest number of larvae. The most effective use of media and 1st instar larvae was obtained with 100 medium cubes and 100 larvae per 8-0z jar. Pink bollworms are now mass reared ill 9-oz waxed-paper pups with ΒΌ in. cubes of medium scattered between layers of cotton.
